WARNING: It is important that this installation

manual is read and understood before

installation. The unit must be installed by a

qualified service technician. Failure to properly

install the unit or attempting to modify it in any

way can be extremely hazardous and may

result in property damage and personal injury

and will void the warranty.

WARNING

The unit weights approximately 86 lbs (39kg).

Ensure a two person lift or use a mechanical

hoist to avoid the risk of injury.

-Do NOT slide the unit on the roof. This may

damage the gasket and result in leaks.

- Position the unit so that the four M8

mounting holes will line up with the four

corners of the square roof hole (Fig 7).

DETERMINE ROOF THICKNESS

-Measure the roof thickness and consult the table on next

page to check if adjustments to the hold down bolt and duct

length are required.

INTERCONNECTION CABLES

Three sets of interconnecting cables must be installed before

installing the rooftop unit. The three sets of cables are for

+12V power, connecting to the furnace, and a

communication cable between the wall mounted thermostat

and the rooftop unit.

+12V Power Connections



Customer provided +12V to the red wire in the

rooftop unit



Customer provided -12V return to the black wire in

rooftop unit

Furnace Connections



Furnace output wire to one of the blue wires in the

rooftop unit



Furnace input wire to the other blue wire in the

rooftop unit

These two connections are interchangeable since

the blue wires are connected to a relay contact in

the rooftop unit

Communication Connection



This is a 4-wire cable (supplied by Dometic) which

connects the wall mounted thermostat to the rooftop

unit.

COC-1 Installation Procedure:

1. Carefully strip and prepare the wires to the

configuration

as shown in Figure 1 using helpful

hints shown in photographs of Figure 2.

2. Hold the clear strain relief cover with bottom facing upward as shown in Figure 3.

3. Lay wire into locator slots, making sure the black wire is placed into the polarization slot as

shown in Figure 3.

4. Press the cable sheath into the integral strain relief slot as shown in Figure 3. Trimming of

ground wire and possibly others will be necessary. Wires must not extend beyond the

locators as shown in Figure 4!

5. While holding the strain relief cover, position the housing’s hinge posts into the hinge slots

and press down until both lock into place as shown in Figure 4.

6. Close the strain relief cover and housing by hand. Place the connector assembly into Molex

tool (preferred) as shown in Figure 5. Squeeze the tool until the connector bottoms out and

the locking latches engage on both sides. OR alternately, squeeze the top and bottom

closed with tongue and groove pliers as shown in Figure 5.1. Pliers must be a minimum of

10" long. Squeeze firmly on both sides, squarely across the connector between ribs A and B

to ensure wires seat completely into slots.

7. Inspect the connector to ensure the wires have been properly engaged into the housing

assembly contacts. A properly terminated wire is fully seated into its proper slots with no

significant bow of the cover. If the wires extend past the insulations tops, the wires must be

re-terminated with a

NEW CONNECTOR. Once

the cover has been closed the connector

cannot be re-used. Failure to comply with this procedure may result in the failure of the

connector.

8. Mating and un-mating the completed connector is illustrated in Figure 6.

Installation procedure for Ducted Models

1. Before installing the rooftop unit, be sure that the communication cable (supplied by Dometic) is installed

between the wall mounted thermostat location and the rooftop unit.

2. Remove self-adhesive backing from roof sealing gasket (11) and place around mounting hole. Apply a modest

amount of silicone sealant around the perimeter of the gasket. Position Cormorant air conditioner (1) over

14inch square hole. Front of air conditioner must face direction of travel.

3. Connect supply power to unit.

4. Connect control cable plug coming from unit to the control cable extension. Plug other end of control cable

extension into the control key pad at the remote location.

5. Cut polystyrene baffle (2) so that it is the same height as the distance from the ceiling to the steel base of the

air conditioner.

Note: The baffle has three sides covered with a self-adhesive foam strip. Cut height from the side without foam strip.

6. Once cut to height insert the baffle into the slot in the plenum deck assembly (3)

Baffle height = ceiling to base height

OPERATING INSTRUCTIONS

- Turn the unit on by pressing the ON/OFF pushbutton once.

- Press the MODE button to cycle through the five mode

selections: COOL, FAN, HEAT, DRY, and AUTO Cool/Heat

modes.

MODE - COOL

- Cycle mode pushbutton to highlight COOL.

- You may select HIGH, MED, LOW, or AUTO fan speeds

by pressing the fan pushbutton. It is recommended that

you choose Auto.

- Now select the desired room temperature (herein

referred

to

as SETPOINT) by pressing the TEMP up or down

pushbuttons. The

readout will flash the setpoint

temperature. Keep pressing the pushbutton until it flashes

your desired set point. In approx. 5 seconds the display will

resume reading the actual room temperature. The

compressor will have a delayed start usually 3 minutes

before unit starts to cool.

Note: Any interruption to the power supply will cause the

unit to delay compressor start up.

MODE – FAN

- For simply re-circulating air, choose the FAN mode. Choose any of the three fan speeds by pressing FAN

button. Note: Temperature pushbuttons are invalid in FAN mode.

MODE - HEAT (model 1511 only)

- To heat, press MODE pushbutton to highlight HEAT.

- Select desired set point temperature by pressing TEMP up or down pushbuttons. It is recommended that

the AUTO fan speed be selected.

- After the delay, the compressor will start. Usually the fan will stop and will not re-energize until the

heat exchanger has warmed and then the fan will start to blow warm air.

MODE - DRY

- The DRY mode is used when the room temperature is close to comfortable but you wish to dehumidify.

- Press MODE pushbutton to highlight DRY.

- Set the temperature to desired set point. Note: the fan speed is locked in LOW.

- The compressor will cycle on and off at approximate intervals of 6 minutes to extract moisture from the air.

MODE – AUTO COOL/HEAT

- This mode has an outdoor defrost mode (indicated by a flashing HEAT LED). During the outdoor defrost

cycle, the MODE pushbutton is inactive.

SLEEP FUNCTION

- With the unit operating in heat or cool mode, press sleep pushbutton to highlight the sleep light. The unit

over the next hour will automatically raise the set point by 2°F. Conversely in heat mode, the set point will

be lowered 2°F.

TIMER FUNCTION

- The timer may be used to turn off the unit in the future (up to 24 hours) OR the timer may be used to turn

on the unit up to 24 hours in the future.

- Press TIMER pushbutton once and the display will flash. Within 3 seconds, press the timer pushbutton

until you have set desired time into the future to turn unit off. A subsequent press of the timer pushbutton

will allow the time to start the unit to be programmed.

LOCK FUNCTION (key symbol)

- This provides a means of locking in the mode and fan settings. To lock, press Temp Down pushbutton

simultaneously with MODE pushbutton. Hold for 3 seconds and the lock indicator will light. To unlock,

repeat above procedure.

Wall mounted Thermostat control. An AC only model

(AC-1361) will not have the furnace pushbutton on the

wall pad unit.

13

DISPLAY SETTING

- To change readout from Celsius to Fahrenheit or vice versa: Press Temp Down pushbutton

simultaneously with the Fan pushbutton.

REMOTE CONTROL UNIT

Many models have a remote control unit which can adjust the thermostat remotely.

- The remote control has duplicated the thermostat input pushbuttons including: the ON/OFF

pushbutton, TEMP UP/DOWN, FAN, MODE, SLEEP, and TIMER pushbuttons

- LEDs in the thermostat control respond to a pushbutton actuation from the remote control unit in

the same manner as it would respond to the pushbutton actuation on the thermostat control.

- The remote control requires a CR2025 battery commonly available.
